As of Monday, I became single again and now all of my plans for this weekend have been screwed up. I have been depressed here lately and I am wanting to take a 3 day tour. The problem that I have is that on a Friday, the high is going to be 52 with a low in the 20s. What I am concerned with is camping in the freezing weather. I have a 30-50* sleeping bag, and my tent is a Kelty Grand Mesa 2. Other than bundling up, what can I do to keep warm? I am mainly concerned during the night time hours where I am going to be sitting still for the majority of the time.
